Multi-Center Medication Reconciliation Quality Improvement Study (MARQUIS)

Sponsor: Society of Hospital Medicine

Location(s): United States


The goal of MARQUIS (Multi-Center Medication Reconciliation Quality Improvement Study) is to develop better ways for medications to be prescribed, documented, and reconciled accurately and safely at times of care transitions when patients enter and leave the hospital. This study, which was funded by the Agency for Healthcare Research and Quality, has produced a set of medication reconciliation tools to reduce medication errors that frequently occur during care transitions. 

The toolkit includes the following materials:

  • The MARQUIS Medication Implementation Manual: A Guide for Medication Reconciliation Quality Improvement
  • Training videos illustrating strategies for taking a medication history and providing discharge medication counseling
  • A return-on-investment calculator for medication reconciliation quality improvement investments
